To all whom 'it may concern:

Be it known that we, JOHN H. RUSSELL and ALBERT A. CARSON, citizens ofthe United States, residing at Ashland, in the county of Ashland andState of Ohio, have invented certain new and useful Improvements inVacuum-Cleaners for Carpets and the Like, of which the following is aspecifcation.

Our invention relates to vacuum cleaners for carpets and the like, andthe mventlon consists 1n a hand power clcanerconstructed and adaptedI tooperate substantially as shown and descr1bed and particularly 'pointedout in the claims.

In the accompanymg drawmgs, Flgure 1 1s a sectlonal side elevation ofthe machine with one of several different forms of sucand Fig. 4 is aplan view on line -fv,

the device, showing agravity hood or skirtingat the front of the suctionhead adapted to close the same upon the floor 'as hereinafter fullydescribed. Fig. 9 is a reduced view of the machine pivotally mountedupon a vertically adjustable standard.

The object and eneral character of the invention are clear y disclosedin the foregoing views, and contemplate a vacuum ma chine adapted toserve the various purposes of such machines forfloor and other work asis now w'ell known, and the machine is projected upon the line ofsimplicity, lightness and convenience of operation, so that a woman canconveniently handle and operate the same for ordinary housework.

To these ends thcmachine is built with a handle- H adapted to be grippedby one hand and a crank C to be grasped by the other hand, and servingto both handle and guide the machine. The said handle part .I-I is shownas provided with two stems or zlegs'Q of sufficient' length to make there- -quired connection with casing G of the suction fan F, and theheader mouth piece or part indicated by D is removably engaged on thetube or pipe E which permanently connects with the fan casing at itsupper end, andthus a rigid structure or frame work is made comprisingthe parts E, G and I-I and the casing J as we shall presently see. 'lhesaid suction head D is provided with a neck or extension 5 sleeved uponthe lower end of tubeE and removably engaged thereon, so that it can betaken off and replaced at will, but said tube and casing G are rigidlyconnected, and a dust receptacle or bag B is hungl upon a hook 6 or thelike at one end u on the tube E and engaged at its upper en over themouth of the ydischarge neck 7 of casing G which opens to the interiorof the said casing and provides an outlet through which the casingdischarges under the operation ofthe fan.

Mechanism for operating the fan is interposed between the hand crank Cand the fan, and the said mechanism is constructed 'to give the maximumof speed to the fan with the minimum of power required in crank C todrive the fan. That is, we have planned ,to obtain the greatest possiblevolume of suction practicable in a device of thls kind with the leastexertion or power to efect such result, and hi h speed as well as easeof rotation of the an are among the things necessary to accomplish thisend. Therefore, we have adopted a system of gears mountedin a casing Jwhich is located over or upon the fan casing G and carries the crankshaft 8 and the said gears and pinions4 for driving the fan. Thesecomprise a relatively large bevel gear 9 fixed on shaft 8 meshing with apinion 10 fixed von a sleeve 11 mounted upon shaft 12 vwhich extendsdown into casing G and carries the fan. The sleeve 11 is provided with apinion 13 upon its upper end and said sleeve with its pinions is free torotate upon shaft 12. Pinlon 13 engages aarelatively small gear 14 aboutthe axis of the large gear 15 which is loosely mounted upon .crank shaft8 and meshes with a bevel pinion 16 fixed upon shaft 12, so that as thecrank C is rotated power is communicated to the fan through theforegoing series of gears, pinions and shafts, and gear 14 is unitary`with gear 15. Now, rctracing the operating connections just described,it is seen that gear wheel 9 meshes pinion 10 110 Which-.drives pinion13 through sleeve 11, and this pinion meshes with the small gear 14 onlarger gear 15 and which in turn4 meshes with the fan driving pinion 1G.

locked on the shaft 12. The fan is driven by this mechanism withcomparative case at a high rate of speed and the desired vacuum resultsin the suction head D. The said suction head comprises the casing orhousfv ing D-as a whole which hasa tubular neck 5 sleeved over theextremity of tube E and is supplemented on the inside by two wings orguards 18 which have rigqht angled end port-ions pivoted upon a shaft 20and constructed to ride or slide .by gravity upon the floor or carpet orother surface over which the tool is being worked, and effeet closure tothe outside air. Both Wings or guards accommodate themselves to anyinequalities inthe surface and to the angle at which the tool `or headmay be held. A screw in each end of the shaft 20 through the wall ofhead D serves as a trunnion therefor and as a bearing. or support forthe wheel or roller 4 outside. No special value is attached 'to thisarrangement as it can be readily changed to an equivalent constructionfor the same purpose. In Fig. l-we show a stationary brush 22 therein,and in Fig. 5 a revolving brush 23. Either may be rused at pleasure andthe 'shaft 20 is shown as engaged in the casing D at its ends andequipped with rollers 4 atits extremities outside said." shell or casingand carrying thesame upon the floor -to lighten the work. l 4,

Figs. 6, 7 and 8 show a modification of the suction .head D'and lwhichwe jdeem the preferable form. In these views the casing D is providedwith a comparatively long tubular neck 24 attached by set screw 25 tothe suction tube E and has a revolving brush 26 mounted therein andprovided with rollers 27 on the ends of its shaft outside the casing andin friction engagement with rollers 28 which carry the device on thefloor and through which and the rollers 27 rotation is imparted to thebrush. The said neck 24 is shown as somewhat enlarged at its lowerportion o n segmental lines and supplemented by a gravity hood` 30 orguard pivotally` mounted at its rear and base upon the spindle or shaft34 of wheels 28 and, like guards 18,makes a complete closure aroundabout the bottom of the said head except at the heel orl rear thereofwhere a rubber or like flexible strip 31 eX- tends lengthwise and isadapted to close off the air from the outside as Well as yield accordingto the position or angle of the tool to the floor. Thus in this as wellas in the other form or forms of the head an effective' skirting of ayieldingl or accommodating nature is interposed about the bottom of thesaid head or vacuum tool which' accommodates itself to all Workingconditions and promotes the efficiency of the suction head as described.

The bag B is of a suitably close Woven duck or drilling which serves tointercept' the dustand yet allows the air to be 'driven through thesame, and. is removably supported on the outside of the machine forconvenience of cleansing.

What we claim is:

1.*1n vacuum cleaning machines, a suc'- tion head, a shaft lengthwisethrough said head and a brush mounted thereon, in combinationwitha'gravity dust guard pivotally mountedin respect to said head andadapted to slide over the floor and close the space about the bottom of,said head against suction from the outside.

2. In vacuum cleaners, a suction head and a brush therein, incombination with a dust guard pivotally mounted on said head at the rearand bottom and extending below the bottom and across the front thereof,and a iiexiblc guard-strip at the rear and bottom of said head and hoodextending downward flush with said dust guard.

In testimony whereof we aiiix our signatures in presence of twowitnesses.
